US 2021/0174752 A1 · DISPLAY APPARATUS AND METHOD OF CONTROLLING THEREOF

Abstract

A display apparatus is disclosed. The display apparatus includes a backlight configured to emit light; a first polarizing plate, disposed in front of the backlight, configured to polarize light emitted from the backlight in a first direction; and a plurality of display panels sequentially disposed in front of the first polarizing plate, wherein each of the plurality of display panels is configured to include a liquid crystal panel and a color filter disposed in front of the liquid crystal panel, and wherein a display panel disposed at a farthest distance from the first polarizing plate from among the plurality of display panels is configured to include a second polarizing plate that polarizes the light of the first direction in a second direction.
